It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL, or between 19.9 and 22.3 mmol/L. It is thus a mass or molar concentration. Still, many instances measure MCHC in percentage (%), as if it were a mass fraction (m Hb / m RBC).CHC is elevated (hyperchromic) in hereditary spherocytosis, sickle cell disease and homozygous hemoglobin C disease. This count is used to give a rough guide to what shade of red erythrocytes will be (i.e., the paler the color the lower the MCHC will be than the standard).
Your hay analysis should show the DM content of your forage. If you are feeding 100% hay and your hay contains 90% DM (or 10% moisture), your 1000 lb horse should be fed 20 lb of hay (18 lb DM/0.9) straight from the bale each day.Clearly, weighing hay is the most effective way to measure the correct amount.our hay analysis should show the DM content of your forage.

Horses can use hay and other roughages as nutrient sources much more efficiently than other nonruminants such as poultry or pigs, although utilization is less efficient than in ruminants. Traditionally, it was stated that a good source of roughage should comprise at least 50% of the total equine ration by weight.It is now recommended that horses receive at least 1.5%â2% of their body weight in forage or forage substitutes such as hay cubes or other high-fiber source daily. 500-kg horse exercising for 1 hr in a hot environment will need to drink 72â92 L of water to replace sweat and evaporative losses. Lactating mares need 12â14 L per 100 kg body wt to sustain good health and milk production.
